The world's first malaria vaccine has cleared its last major hurdle on its way to being approved for real-world use. The European Medicines Agency (EMA) — the regulatory group in the European Union which roughly parallels the FDA — gave a positive opinion of the vaccine, saying it is safe and effective to use in babies at risk for the parasitic disease. With this "green light," the World Health Organization will decide later this year whether or not to recommend the shot for use.
